PIPC Roll Call Datasets

House Votes

This version of the PIPC Roll Call Dataset represents the latest iteration in a project that was started by David Rohde started and continued by many scholars over many years. This newest version now scrapes information from the Clerk of the House nightly and codes the “vote type” (e.g. amendment, final passage, moving the previous question) variable using a python script rather than relying on the judgment of individual coders. For the first time, the dataset will now always include the most recent votes and vote type codes. As computer program codes all votes from the 101st Congress to the present while votes from the 83rd-100th Congress are the original hand-coded votes. Please read the codebook for additional information.
